If ICO wasnt been plague by scammers acts ICO will way better than IEO, ICOs are programmed to run on the projects very own website and no any third party involvement at all so any fund raised will go directly to the dev or project team, no loss of funds to scam exchanges,after some successful IEO fund raise on some exchanges they dont bother to send the funds back to the project teams
I agree with you, developers are the most affected in this IEO issues. I ones heard that a developer paid about two btc to hold an IEO on a cryptocurrency exchange and after the period of the tokensale was told that no token was sold after there was huge movements in the exchange which was planned to make it seem that the tokens are been sold out.
